Learning i'm pronouncing a word wrong does not change the way I pronounce a word. It only changes how I pronounce it in front of other people, like, mine sounds better don't know what to tell you
화학소재, 의약품, 플라스틱 등 우리가 소비하는 대부분의 공산품은 유기화학 반응의 산물이다. A라는 물질이 화학반응을 거쳐 B라는 물질로 변할 때 짧은 수명을 가진 중간단계를 거치는데, 이 중간물질의 하나가 ‘탄소양이온’이다.* 탄소양이온(Carbocation) : 양전하를 띤 탄소 원…
The fact that atoms that we normally think of as electron-wthdrawing (nitrogen, oxygen, chlorine) can actually be electron-donor groups is probably one of the most difficult factors to wrap your head around in Org 2.

im having trouble in understanding carbocation reaction 😭
ELECTROPHILIC ADDITION OF ALKENES
One day an alkene was just trollollolling along, minding his own business, as alkenes do. What he didn't realise that the double bond C=C he posessed in his stomach, was actually a really HIGH AREA OF ELECTRON DENSITY :o
An area that ELECTROPHILES are attracted to. An electrophile is an electron-deficent species that takes part in an organic reaction by attacking areas of high electron density in another reactant. :o An example of an electrophile is HBr, hydrogen bromide.
This electrophile was all alone. He only had a partially positively charged area. All he wanted was some company from some fellow electrons. He couldn't help but be attracted to the double bond in the alkene.
Fortunately, the alkene could sympathize with the electrophile. The electrophile accepted a pair of electrons kindly donated by the double bond in the alkene.
The alkene had been hoping for change, some transformation. He was bored of the alkene life. He wanted to be free. He wanted to grow up to be a haloalkane ever since he was little boy.
In order for this to happen, a positive ion a CARBOCATION forms. A negatively charged ion (in this case Bromide) and forms a bond with the carbocation.
And everyone lives happily ever after.
